Adjustments to widget registration

- use wmWidgetMapType_Params struct instead of passing around same args (not always in same order).
- split WM_widgetgrouptype_find create behavior into WM_widgetgrouptype_ensure
- rename WM_widgetgrouptype_new to WM_widgetgrouptype_register
(since it has an unregister argument)
- add WM_widgetgrouptype_register_ptr argument, which doesn't need to perform a search.

Merge branch 'master' into wiggly-widgets

RNA subclass widgets, one step closer to working again

- expose '3D' flag via bl_options.
- expose 'Label' via bl_label
- create new widget-group map when its not already existing.

This still misses new keymap callback, will add next.

Move struct member 'is_3d' to a flag

Means we don't have to add new args for each type-option and
makes is useful for RNA-subclassing.

Minor rename/cleanup

avoid hard-coded array sizes

Fix leak freeing widget which was highlighted

Correct fix for widget memory leak

Fix out-of-bounds access in manipulator_get_axis_color

Pass in named of variables to macros

Avoids confusion as to where vars are declared.

Previous commit was wrong

this is leaking still, but this free call is redundant - needs further investigation.

Fix memory leak w/ widget operator properties

Fix leak w/ GLU quadrics
